Several internal utility functions are exported for convencience in case dependent packages can make use of this functionality.
Usage
set_names(object = nm, nm)
paste_enum(x, sep = ", ", conj = " and ", quotes = "`")
coal(..., fail_null = TRUE)
reval(x)
reval_if(x)
last(x)
unlst(x, recursive = FALSE, use_names = FALSE)
pkg_name(env = parent.frame())
pkg_version(pkg = parent.frame())
pkg_file(..., pkg = parent.frame())
pkg_avail(...)Arguments
- object, nm
- x
Character vector to
base::paste()- sep, conj
Separation strings for all but last and last positions
- quotes
Quotes to wrap each entry in
xwith- ...
Set of objects to iterate over
- fail_null
Error if no non-null objects are present
- recursive, use_names
See
base::unlist()- env
An environment that is resolved to a package name
- pkg
A string.valued package name or an environment passed to
pkg_name()
Value
Function set_names() returns a names object, paste_enum() a
string, coal() the first non-null object and unlst() performs the same
action as base::unlist() but with differing defaults.
